Now, a new study suggests that's especially true when it comes to one fairly common health issues.

A team of U-C Davis researchers have found that mothers who had fevers during their pregnancies were more than twice as likely to have a child with autism or a developmental delay than mothers who controlled their temperatures with medication or those who didn't have a fever at all.

To reach their conclusion, the scientists studied an ethnically-diverse population of more than 1,100 Californian children ages two to five.

The study, published in the Journal of Autism and Developmental disorders, is believed to be the first of its kind.
